Based partly on Knuth's Seminumerical Algorithms (as best as I could manage), and written in C, BigMath
aims to be light-weight and fast. Its original implementation was for use within a kernel
extension - thus size and speed were essential.

This release includes support for calculating nth roots, which puts me one step closer to fast factorial support. Also, I've added string-to-bignum support, which let's one do this sort of thing: bignum_cstr_base(mynum, 10, "1234567890", 10). Lastly, I've made a little progress on my calculator gui, which is included. It's not quite at the point of being useful yet.
